Case study: Loss of vision or something else?

I was contacted by the family of Mr JM, a retired teacher. They were very worried that having always read every newspaper and copy of The New Zealand Listener from cover to cover, as well as having a library of books he was looking forward to getting into, he was now complaining he couldn’t read. This was despite numerous eye clinic appointments, new glasses and various attempts to supply magnifiers and ready-made spectacles. Concerned, they felt his loss of vision was starting to impact his quality of life and he was sinking into depression.
